Description

FABRIC SOFTENERS FIELD OF THE INVENTION The present invention relates to fabric softening compositions comprising a hydrophobically modified cationic polymer comprising a hemicellulose backbone or a starch backbone, as well as processes for the production and use thereof.

BACKGROUND Conventional fabric softening compositions typically comprise a solvent phase and particulates comprising a fabric softening active. Such particulates can be vesicles. Additionally, a fabric softening composition may comprise other materials including softening actives that are found in the fabric softening composition but outside of the aforementioned particulates. Regardless of where such softening actives are found, it is preferred to increase the deposition efficiency of such softening actives since this may improve the performance of the fabric softening compositions and / or reduce the cost of such fabric softening compositions. The deposition efficiency of fabric softening compositions is typically increased by the addition of deposition polymers. Unfortunately, as the level of deposition polymer in a fabric softening composition increases, the stability of the fabric softening composition decreases. Eventually, as the level of deposition polymer increases, the particulates of the fabric softening composition are separated in volume, which manifests as a phase separation or a change in the viscosity of the fabric softening composition occurs, which causes the gelling of the composition.

The applicants recognized that the phase separation is driven by the flocculation induced by reduction due to the excess of deposition auxiliary polymers in the solvent phase of the fabric softening composition and that the gelation is due to the deposition auxiliary polymer deposition particulates. . Applicants discovered that successful selection of the type and level of the deposition polymer can result in fabric softening compositions that exhibit improved deposition of fabric softening actives without significantly increased stability negatives. Such deposition polymers must have a high adsorption affinity for the aforementioned particulates, which minimizes the amount of polymer in the solvent phase of the fabric softening composition and produces a low or no tendency to bind to the particulates. As long as the deposition polymer is correctly selected, the formulator can use increased concentrations of such a polymer to achieve the desired deposition of the fabric softening active without the stability negatives mentioned above.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to fabric softening compositions comprising a hydrophobically modified cationic polymer comprising a hemicellulose backbone or a starch backbone, as well as processes for the production and use thereof. Such compositions show an improved deposition of fabric softening actives without significantly negative stability.

Increases that may include poor silicone deposition, fibrosity and / or poor viscosity.

The first orifice holder 15 has inner walls defining a conduit through the first orifice chamber 14.

The second orifice unit 1 1 is practically the same construction as the first orifice unit 10.

The hole units 10 and 11 are arranged in series within the hole component 5. Several orifice units may be arranged in series within the hole component 5. Each hole plate may comprise at least one hole. The holes can be configured anywhere on the hole plateas long as they allow the flow of liquids through the apparatus A. Each orifice plate may comprise at least one orifice configured in a different orientation to the next orifice plate. In one aspect, each orifice plate comprises at least one hole that is disposed so that it is off center compared with the hole in the neighboring orifice plate. In one aspect, the size of the hole within the orifice plate can be adjusted in situ to make it larger or smaller, i.e. without changing or removing the orifice plate.

The first orifice support 15 and the second orifice support 22 can be of any suitable shape or size, as long as they secure the first orifice plates during operation of apparatus A. Figures 1 and 2 show an example of the orientation and size of an orifice support 22. In another aspect, the orifice support 22 can extend only half the distance between the second orifice plate 20 and the first orifice plate 12. In a further aspect, the second orifice support 22 can extend only a quarter of the distance between the second orifice plate 20 and the first orifice plate 12.

In one aspect, the orifice plate 12 is hinged so that it can be rotated 90 ° about its central axis. The central axis can be any central axis, as long as it is perpendicular to the center line 27, which runs along the length of the apparatus A. In one aspect, the central axis can be along the axis line 28. By allowing the hole 12 to be displaced 90 ° about its central axis, the accumulation of excess material in the first orifice chamber 14 and / or the second orifice chamber 23 can be more easily eliminated. size and / or orientation of the first orifice support 15 can be adjusted to allow rotation of the first orifice plate 12. For example, in one aspect, the first orifice support 15 can be released and moved in an upstream direction in opposite direction of the first orifice plate 12 to the premix chamber 2. The orifice plate 12 can then be released and rotated through 90 °. When the apparatus A is clean, the first orifice plate 12 can return to its original operating configuration and then if present, the first orifice holder 15 returns to its original operating position. The second orifice plate 20 and, in addition, any additional orifice plate, may also be hinged. The second orifice holder 22 and any other orifice supports present may also be adjustable in the manner as described for the first orifice holder 15.

Either two orifice plates must be different from each other. In other words, the neighboring orifice plates should not be in contact with each other. By "neighbors" in the present description, refers to the next series orifice plate. If two neighboring plates are in contact with each other, the mixing of the liquids between the orifices is not achieved. In one aspect, the distance between the first plate of holes 12 and the second plate of holes 20 is equal to or greater than 1 mm.

The elements of the hole component 5 form a channel defined by walls having a substantially continuous inner surface. As a result, the hole component 5 has few, if any, cracks between the elements, and may be easier to clean than previous devices. Any connection between adjacent elements can be elaborated in detail by mechanical joining techniques, such as polishing or electric grinding, in such a way that liquids can not enter the joints between such elements even at high pressures.

The hole component 5, and the components thereof, can be made of any suitable material or materials.

The elements may furthermore be formed from a solid part of one of the materials specified above, which may or may not be coated on at least a portion of its surface with one or more other materials specified above. Since apparatus A requires lower operating pressures than other shear, turbulence and / or other devices Cavitation, is less prone to erosion of its internal elements due to mechanical and / or chemical wear at high pressures. This means that it may not require costly coatings, such as diamond coating, of its internal elements.

In other aspects, the hole component 5 with the first hole 13 and the second hole 21 in it may comprise a single component having any suitable configuration, such as the configuration of the hole component shown in Figure 2. This component Simple could be manufactured from any suitable material, which includes, but is not limited to, stainless steel. In other aspects, two or more of the elements of the hole component 5 described above could be formed as a single component.

The first orifice 13 and the second orifice 21 are configured, alone, or in combination with some other component, to mix the fluids and / or produce shear, turbulence and / or cavitation in the fluid (s), or the mixture of the fluids. The first hole 13 and the second hole 21 can each be of any suitable configuration. Suitable configurations include, but are not limited to, in the form of a slot, eye shape, cat eye shape, elliptical, triangular, square, rectangular, in the shape of any other polygon, or circular.

This allows an additional liquid to be added to the liquids that have come out of the orifice component 5.

Furthermore, it is desirable that the interior of the apparatus A be virtually free of any cracks, crevices and cracks so that the apparatus A will be easier to clean between uses. In one aspect of the apparatus A described in the present description, the orifice component 5 comprises several elements that are formed in an integral structure. This integral structure of the hole component 5 fits as a unit in the housing of the premix chamber and does not require a support block to hold the same in place, eliminating such cracks.

In addition, many other aspects of the apparatus A and components thereof are possible. The pallet clip 17 could be configured to hold more than one pallet 16. For example, the pallet clip 17 could be configured to hold two or more pallets.
